I am having some problems with the BindGridView method of CustomGridView Control. Following are the error details. If anyone could help me I 'll be really thankful .......
System.MissingMethodException was unhandled by user code

I may be wrong but in my view the problem is in the following line of code
with sortExpression
base.DataSource = objectType.InvokeMember("SortByPropertyName", BindingFlags.InvokeMethod, null, ListObject, new object[] { sortExpression, sortDirection = SortDirection.Ascending });

I am also having the same problem and this has stalled my learning process for the last two weeks. I have tried all I could to no avail. Pls pls anybody out there who can help?????

Dear Goodshow,
could you please send me your code. In my case there was a typing error.
I was using small case instead of upper case.
So please check your code carefully.
I hope this will help
Best Regards
Zia

Dear GoodShow
I was using this
sortDirection = SortDirection.Ascending
while it should be this
sortDirection == SortDirection.Ascending
Please note the difference of =.
I hope this will help
Best regards
Zia

When I run the program in Chap 4 and click on the Users link under Security, this part of the code is highlighted:

base.DataSource = objectType.InvokeMember("SortByPropertyName", BindingFlags.InvokeMethod, null, listObject, new object[] { sortExpression, sortDirection == SortDirection.Ascending });


followed by this message in the error messagebox:

Method 'V2.PaidTimeOffBLL.Framework.ENTUserAccountEOList. SortByPropertyName' not found.

Please help! What am I doing wrong? Thanx for any help in solving this.
